Specification of Letters Patent.

PatentedJune 16, 1908.

Application filed March 27, 1907; Serial No. 364,780.

To all whom it may concern:

Be it known that I, SIDNEY U. BARR, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Window, of which the following is a full, clear, and exact description.

The invention relates to windows, such as shown and described in the Letters Patent of the United States, No. 797 ,835, granted to me on August 2, 1905. V

The object of the present invention is to provide a new and improved window, which is completely dustproof and air tight, and arranged to permit easy opening and closing 1 of the sashes without danger of the sashes sticking, and to allow convenient removal of a sash for repairs or other purposes and without requlrmg detachment of the pane or other parts of the sash.

The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then'pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 1s ansinner face view of the improvement; Fig. 2 is an enlarged cross section of the same on the line 2-2 of Fig. 1; Fig. 3 is an enlarged inverted sectional plan View of the same on the line 3 -3 of Fig. 1; Fig. 4 is an enlarged inverted sectional plan viewvof the mullion and one. of the sashes partly 0 en; Fig.-5-is an enlarged cross section of .t e-improvement on theline 5-5 of" Fig. 1; Fig. 6 is an enlarged plan view showing the mechanism for turning a sash'into an a open or a closed position; Fig. 7 is a sectional side elevation o the same; Fig. 8 is an enlarged cross section of theimprovement on the line 8-8 of Fig. 1 Fig. 9 is a like view of the same on the line 9 -9, of Fig. 1 Fig. 10 is an enlarged sectional plan view of the mechanism for operating the sash gearing, the section being on the hue 10-10 of Fig. 11 and Fig. 11 is a sectional side elevation of the same on the line 11-11 of Fig. 10. r

The window, as illustrated in Fig. 1, is provided with the main sashes A, A and the transom sashes A A and the said sashes A, A, A and A are center-pivoted and mounted to swing in the window frame B. For the either threaded apertures C C can be locked in its raised or retracted position.

.to engage a bearing 'in the purpose described the sashes A, A and A are mounted to swing on top and bottom pivots C, C and are adapted to be locked against accidental opening by manually controlled bolts D, preferably of the extension or Ore morne type. The sash A is mounted on top and bottom ivots 0 C, pivot C is a apted to be turnedby an actuating mechanism under the control of the operator, the said mechanism serving toaho d the sash A locked in an open, partly-open or a closed position. 1

The top ivot O for each of the sashes A, A and A (see Fig. 8) is mounted to slide vertically in the top cross bar A of the corresponding sash and is adapted to engage a bearing B in the cross bar B or B of the window frame B. The pivot O is locked in place in either an extended or a retracted position by the use of a clamping screw E screw ing in the threaded hole 0 or C formed in the pivot O one above the other, as plainly indicated in Fig. 8. The clamping screw E eX- tends loosely through an enlar ed transverse opening A formed in the cross ar A and the outer end of the said clamping screw E is provided with a head E adapted to engage a seat A formed on the inner face of the corresponding cross bar A. Now on unscrewing the clamping screw E the pivot C can be raised or lowered by the use of a nail or other tool, so as to move the pivot G in a vertical direction in or out of engagement with the bearing'B by engaging the clamping screw E with The lower pivot C A, A and A (see Fig. 9) is mounted to slide or C the pivot for each of the sashes of which the top vertically in the bottom cross bar A of the v corresponding sash, and the bottom pivot C for each ofthe main sashes'A, A is adapted? sill B of the win-' dow. frame B, while the bottom pivots C, C for the sashes A A are adapted to engage bearin s in the cross bar B of the window frame The bottom pivots C and C are alike in construction and each is provided with a number of threaded a ertures'C, C",

G adapted to be engaged y a clamping.

screw E similar to the clamping screw E and having a head E for engagement with the bottom cross bar B of the corresponding sash A, A, A andA Now by unscrewing the'clamping screw E the pivot G can be readily raised by the use of a nail or other tom of the corresponding cross bar A rests tool, and then the pivot can be locked in a raised or disengaged position by rengaging the clamping screw 2 with the lowermost [aperture O of the pivot O.'

In order to insure an easy swinging of each of the sashes A, A, A and A the pivotal botand travels on a ballbearing (see Fig. 9), con sisting of aring F in which are held balls F projecting beyond the top and b'ottomfaces of the ring F, the balls being engaged at the top by a ring-shaped bearing F fitting in a l recess 1n the under side of the crossbar A and secured to the latter by screws or the like (not shown). The lower ends of the balls F rest on a ring-shaped bearing F seated in'a recess in the sill 4 or the cross bar B the said recess being sufficiently deep to also contain the ball hearing, as plainly indicated in Fig. 9. Now by reference to this figure, it will be seen that the ring F and the bearings F F are concentric with the pivot pin C (or C and the latter when raised passes out of'the bearing. F and ring F, to allow of removing the sash at the time the corresponding upper pivot C or C is retracted.

N ow when it is desired to remove either of the sashes A, A and A the sashes are held locked in a closed position by the locking bolts D and then the operator, by removing the clamping screws E and E obtains access to the top and bottom pivots C, C of the said sashes, to retract the same, that is, to lower the to pivot C and to raise the bottom pivot O. hen this has been done, the retracted pivots can be locked in place by the corre sponding clamping screws E and- E after which the operator, unlocks the bolts D to thus free the sash in the window frame and to allow removal thereof without re uiring removal of the pane or other mem er of the Slide vertically bearing formed in the top cross bar A of the' sash or window frame.

I As previously mentioned, .the bottom pivot C of the sash A is like the bottompivot C, but the topzpivot C for the sash A is made square (see in a correspondingly shaped sash A This top pivot C is adapted to be locked in an extended or retracted osition by a clamping screw E having a hea 'E and 1 and 6), ing bar G with a rack G in mesh with a ear the side bar 13 wheel Gr secured on the upper end of a s aft H j ournaled in suitable bearings arranged in 1g. 5), and is adapted to window frame of the window frame B (see J Figs. 1, 10 and 11 A sa pin G5 on the top cross bar B? (see Fig. 6).limits the 'slidingmotion of the extensible rack formed of the racks G, G and the connecting bar G The lower end of the shaft H terminates in the sill B and is provided with a wormwheel H in mesh with a worm H secured on a transversely extending shaft H journaled' in suitable bearings arranged on-the sill B.

The square end H of the shaft. H extends arranged intoan enlarged aperture B formed on the inner face of the sill B, so as to permit convenient engagement of a turning crank with the square end H, to allow the operator toturn the shaft H whenever it is desired to swing the sash A on its pivots C and C By using connecting bars G of different length, it is evident that sashes of different width can be readily accommodated without requiring a change in the construction of the gearing shownand described.

Eachof the sashes A, A, A and A when moved into a closed position interlocks with the Window frame, and for this purpose the detail construction of the sashes and windowframe is as follows: The cross bars A and A of each sash are connected with the stiles A and A, and each of these parts of the sash frame is formed of a frame memberI and an interlocking'stop member I, the several members I of a sash forming the pane frame 'for the reception of the pane J of glass or othertransparent or translucent material.

The members I and I of each sash part are screwed or otherwise fastened together and theircontacting faces are provided through out their length with registering grooves, for the reception of apin K made of wood or other material, and serving to render the joint between the said'contacting faces of the members I and I dustproof and. air tight;

The window-frame B has each of its indiv'idual parts, that is, the cross bars B B the sill B, the side bars B and B? and the mullions B built up in the same'zmanner, that is,

each window frame part is provided with an wise secured to the window frame part mentioned, and a pin K similar-to the pinK is fitted into the registering grooves between 1 the contacting faces, "to render each window.

The

forthe sash parts and the frame part'dust roof and air tight. members I and parts are alike in cross section, so that a window sash and a window frame can be readily and cheaply built up from but few strips of diflerentcross sectional shapes, the strips being cut into proper length to suit the size of the window. The

interlocking stop members I for each sash extend partly on the outer face of the sash and partly on the inner face of the sash, and

' interlocking stop member I bolted or other- I the stop members Pof the window frame B are correspondingly'arranged (see Figs. 1, 2

and 3), the stop members I overlapping each when a sash is turned at the center pivots C,

C (or C C into a closed position, then the corresponding stop members I and I interlock with each other.

In order to render the joint'between the interlocking stop members I and 1 air tight and dustproof when the sash is closed,-pack-, ings or cushions L are employed, each packing being tubular and preferably made of a piece of rubber tubing, through whichextends ametallic rod L secured by screws or other means to the correspondin member I of the sash, as plainly illustrate in Figs. 2, 3 and 4. The packings L are arranged in registering rabbets or grooves" formed on the contactin surfaces of the members I and I of the sas es/and window frame, but as this construction of the 'acking is the same as that'more fully described in the Letters Pat-- ent of the United States above referred to, it is not deemed necessary. to describe the same any further.

Although sash frame and I- have shown the parts of the window frame of tubular metal, it is evident that I do not limit myself to the use of metal, as wood or other materials may be substituted.

Having thus described my invention, '1 claim as new and desire to secure by Letters Patent:

1. A window provided with a window frame and a sash, center pivoted on the said frame, and having stop members'interlocking with stop members of the said window frame to form a continuous joint, each stop member being tubular and approximately rectangular in shape.
